Since others are able to reproduce the error, any help over there would be very appreciated. [1] The last post suggested it may be an R issue rather than an OpenBLAS one, but I wanted to be more sure of that before going to R developers, especially given their comment about the --with-lapack flag: "Please do bear in mind that using --with-lapack is 'definitely not recommended': it is provided only because it is necessary on some platforms and because some users want to experiment with claimed performance improvements. Reporting problems where it is used unnecessarily will simply irritate the R helpers." https://cran.r-project.org/doc/manuals/r-release/R-admin.html#LAPACK -- Kyle
